How can the session management in the PHP code be optimized for better security and efficiency?

To optimize session management in PHP for better security and efficiency, it is recommended to regenerate the session ID periodically to prevent session fixation attacks and to limit the session data stored in the session to only necessary information. Additionally, storing session data in a secure manner, such as using encrypted cookies or server-side storage, can enhance security. 

// Start the session
session_start();

// Regenerate session ID periodically
if (isset($_SESSION['last_regenerated']) && $_SESSION['last_regenerated'] < time() - 30) {
    session_regenerate_id(true);
    $_SESSION['last_regenerated'] = time();
}

// Limit session data to necessary information
$_SESSION['user_id'] = $user_id;

// Store session data securely
// For example, using encrypted cookies
setcookie(session_name(), session_id(), time() + 3600, '/', '', true, true);
